Key Features
- Hardened Steel Construction — Manufactured to the hardened specification Genie requires, delivering the load-bearing capacity and wear resistance the original design demands.
- Exact Dimensional Conformity — Cut to the precise .75 diameter and thickness tolerances of the OEM part, so it seats correctly against mating fasteners and surfaces without shimming or adjustment.
- Broad Fitment Across Genie Families — Compatible with Z and ZX articulating booms, S-series telescopic booms, GTH telehandlers, TZ trailer booms, and AL light towers, making it a versatile stocking item for mixed Genie fleets.
- Structural Fastening Integrity — A hardened flat washer distributes clamping load evenly across the joint surface; a worn, deformed, or undersized washer allows fasteners to loosen under vibration and load cycling, leading to joint failure.
A flat washer sits between a fastener — typically a bolt head or nut — and the surface it clamps, spreading the load over a wider area so the fastener does not pull through or damage the material beneath it. The hardened specification means this washer is rated for joints that carry significant clamping force or cyclic stress, where a standard-grade washer would deform or flatten over time. When a washer loses its shape or is replaced with an incorrect grade, the fastener joint becomes unreliable and the connected components are at risk of working loose during operation.
